• The No. 1 quarterback snaps have been split evenly the first two days between Danny Etling and Austin Appleby. Is it David Blough's turn? We'll find out if the freshman is seriously in the mix.

• Does B.J. Knauf finally practice? He's missed the first two days after suffering a head injury last month during 7-on-7 drills. Lots of receivers to evaluate. Freshman Gregory Phillips looks good, but it's only two days.

• Watching the offensive line. David Hedelin, who will miss the first three games because of NCAA imposed suspension, continues to get first and second teams reps. Jack DeBoef remains the No. 1 left tackle but he'll need a backup or several tight ends by his side. How is JUCO transfer Corey Clements holding up?

• Leroy Clark played some nickel Tuesday. We'll see if he's back in the same position.

Bonus item: The Las Vegas Sports Hut has spoken: Purdue is a 12-point favorite over Western Michigan in the Aug. 30 season opener. This is the first time Purdue has been a double-digit favorite against an FBS program since Sept. 29, 2012 when it played Marshall.

Bonus item II: Purdue has added Eastern Michigan to the 2018 schedule. The game is Sept. 8 after the season (and Big Ten) opener against Northwestern and before Missouri comes to town. Also, expect an announcement shortly on the 2017 season opener against Louisville (we've told you about this before) at Lucas Oil Stadium.
